INSPECTION

CAUTION:

The level of ATF varies with fluid temperature. Pay attention to the ATF temperature when checking ATF level.

1. Raise the ATF temperature by driving a distance of 5 — 10 km (3 — 6 miles). Otherwise, idle the engine to raise ATF temperature to 70 — 80°C (158 — 176°F) on Subaru Select Monitor.

2. Make sure the vehicle is level.

3. After selecting all positions (P, R, N, D), set the select lever in “P” range. Idle the engine for 1 or 2 minutes, and measure the ATF level.

Upper level

(C)

Lower level

4. Make sure that ATF level is above the center between upper and lower levels.

NOTE:

When the transmission is hot, the level should be above the center between upper and lower levels, and when it is cold, the level should be found below the center of these two levels.

5. If the ATF level is below the center between upper and lower levels, add the recommended ATF until the fluid level is found above the center between upper and lower levels.

NOTE:

Do not fill ATF up to the upper limit mark on the “HOT” side when the ATF temperature is less than 70°C (158°F) as overfilling can cause problems.

CAUTION:

Be careful not to exceed the upper level.

If any ATF is spilt on the exhaust pipe, wipe it off with a cloth to avoid emitting smoke or causing a fire.

Be sure not to add ATF up to the upper limit mark when the transmission is cold because that will be the cause for excessive filling of ATF, and will cause transmission failure.

6. Check the ATF level after raising ATF temperature to 70 — 80°C (158 — 176°F) by running the vehicle or by idling the engine again.

7. Check that there are no ATF leaks.

Check for leaks inside of the transmission. If there are leaks, repair or replace the gasket, oil seals, plugs or other parts.
